SEAT CUSHION.

I .Application led May 29, 1926. Serial No. 112,565.

This invention relates to seat cushions of i the enclosed spring type, and an objectof the invention is to provide an enclosed spring seat cushion constructed and arranged to be used interchangeably upon different seats or supports either as a supplement to the cushion structure of such seats or supports, or to' supply a needed cushion where the same is lacking.

Another object of the invention is to provide an improved cushion constructed and designed to be used optionally as a seat cushion or a cushion for the back and comprising series of coiled springs retained and confinedy in a novel cooperative relationship to obtain the desired flexibility of the device at every point and in every direction, to permit bending adjustment of the device in conformity with the contour of the seat or 4'support upon which it is placed and the pressure to whichV it is subjected. g j Another object of the invention is to providean improved seat cushion embodying the l proved cushion.

rthe line 3 3 of Fig.

structure last above mentioned and characterize'd by suiicient stiffness so that it-will remain in an uprightposition without falling or bending upon itself and yet will bend and yield to the contour of the seat or support to which it is applied and still provide a yielding cushion for the user.

, Another object of the invention is to provide an improved seat cushion of the enclos/ed spring type which is flexible in every direct-ion and at every point and comprising novel means for confining and retaining the springs in proper cooperative relationship for the purposes stated'.

Another objecto the invention is to pro-,

structure mentioned in which the spring con# ining lstructure is provided with improved means for permitting passage of air into and out of the cushion. l i l Other objects of the invention will appear vfrom the following description', reference bein madeto the drawings in which ig. 1 is a top plan or front view of my im- Fig.2is aside elevation.. i j

ion at Fig. 6' is a diagrammatic view showing more plainly the construction ot' the spring confining means shown in Fig. 5.

Fig. is a diagrammatic view showing more clearly the structure at the side of the spring coniining means shown in Fig. 4.

The spring confining enclosure shown comprises a stripof lmaterial 1, preferably of coarse weave, such as burlap, having its ends secured together by a row oi' stitches 2, or otherwise, to provide upper and lower confining walls for series of springs 3. The springs 3 are coiled and, by their inherent resiliency, maintain the cushion expanded. yThe springs 3 are separated from each other by a longitudinal series of partit-ions 1 and by transverse partitions 5 which partitions provide a separate compartment for each spring. These partitions have their upper and lower edges folded against the inner sides of the upper and lower parts ot' the enclosure 1 and secured thereto by stitches 6. These partilationship to each other and prevent the coils overlapped. The springs are zittached to the respective partitions by l tying elements or threads 5a. springs is completed by a pair of longitudinal side members 7 having their upper and lower edges Secured to spring enclosure describedI forming a padding opposite the ends of all ofthe springs 'to prevent damaging or undesired effect-s b the spring ends. ,This section 9 of matting or the like may be in a continuous strip extendino' throughout the length vof the cushinner edges of which are connected and attached to the matting by rowsl of stitches 11,

hoth upper and .lower sides and across y tions 4 and 5 retain the springs 3 in proper rel The inner enclosure for the l the edges of the part 1 by while the ends of the matting and the strips are attached'together by arow of stitches 12 j (Fig. 6). The parts 1 and 9 being of carsel Weave permit the passage of air to and from the inside of the cushion so as to obtainthe greatest benefit from the springs.

. The cushion as already described is encloth' 13 extending around the cushion from closed within a case comprising a section of end to end and having its ends extended and enclosed respectively in an edge binding 14 extended in superimposed. relationship and at-tached together by one 0r more rows of stitches 15. Phe sides 16 of the case have their longitudinal edges folded-against the inner sides of the case portion 13 the outwardly extending marginal edges of said portion 13 and sides 116' being enclosed by strips offbinding 17 secured thereto by rows of stitches 1 8.

The upper or front side of the case is provided `with an opening 19 and a section 2O of material of coarse weave to permit passage of air therethrough is secured in said opening. The edge of the section 20 is overlapped by the edge of the case 13 around the opening. A strip of .edging or binding 21l encloses the edge of the easel?) around the opening 19 and the three overlapping part-S13, 2O and 21 are secured together by rows of stitches 22.

Preferably the springs 3 are of graduated,`

lengths from thelower or front end of the cushion to the rear or upper end,as will be readily understood by reference to Figs. 2 and 3. The cushion constructed as shown and described possesses advantages `of improved shape, elasticity and flexibility and is capable of use in various places. tion may be varied within the range of equivalents without departure from the nature and principle of the invention.

Contemplatiiig such variations and without restricting myself unessentially in any par'- t-icular I claim and desire to secure by Letters Patent:

1. A transversely and longitudinally ex ible cushion comprising coiled springs, a fibrous non-metallic textile case confining said springs and extending across the opposite ends of said springs, straw mattin secured around said case opposite both en s of said springs, and anouter fibrous non-iiietallic textile case enclosing all of said parts.

2. A cushion comprising series of rows of The construccoiled springs, an inner case enclosing said springs, a layer of material of coarse weave against the upper and lower sides of said inner case, an outer case enclosing all-of said structure and provided with an openingthrough one side, and a section oi material provided with numerous openings therethrough tillinnr said opening and secured to lthe margin o said'outer case around said 4. A cushion comprising a series of longi.

tudinal rows of coiled springs, partitions separating all of said springs from each other, an inner ease of non-metallic pliable material enclosing all of said springs and said partitions, aneouter case ot' non-.metallic pliable material .enclosing the entire cushion structure, and. a layer of non-metallic pliable material of coarse weave between said inner and outer cases opposite both ends of said springs.

5. A cushion. comprising series of longitudinal and transverse rows'of coiled springs, iexible and pliable partitions separating all of said springs from each other, an inner ilexible non-metallic case enclosinU-said springs and said Jartitions, a layer o/'fleXible noninetallie' p iable material of coarse weave extending around said inner case in one direction and lying opposite both ends of all of said springs, and an outer case of non-metalic pliable material enclosing all of said cusliion structure and together with said inner case and said layer of material forming three layers of non-metallic pliable material oppo` site both ends ofsaid springs.
